The School Committee decided last week to train its staff in the safety program called ALICE (alert, lockdown, inform, counter, and evacuate) after a recent presentation on the program by Police Chief Paul Shastany. The program trains staffers how to respond to attacks by an armed intruder, and can include such actions as throwing things at a shooter. “After carefully comparing the current lockdown procedure to the enhanced choices of ALICE, the administrators, the police department, and I felt we had to recommend moving towards ALICE,” Superintendent of Schools Marguerite Rizzi said in an e-mail to the Globe. Rizzi said the schools will conduct a community information session Wednesday at 7 p.m. at the O’Donnell Middle School. Shastany had urged committee members to adopt ALICE at their Feb. 12 meeting.
